Would an impedance swamped attenuator work with a 2 ohm load?

    Would an impedance swamped attenuator work with a 2 ohm load? For instance, a Weber Mass Lite attenuator with a Super Reverb. The description says that it works with 4, 8, and 16 ohm impedances. I know that a 4 ohm attenuator will work with a Super Reverb, so will this? Thanks!

    I don't think you'd want to try that. Why would you think an attenuator rated for 4, 8 or 16 will work on a 2 ohm load?

    Because a 4 ohm attenuator is fine with a 2 ohm load, so I was curious if the same was true for an impedance swamped attenuator which can operate at 4 ohms.

    What makes you think a 4 ohm attenuator is "fine" with a 2 ohm load and what is "an impedance swamped attenuator"?

    Weber says some of their attenuators are "impedance swamped" to match different impedances. And the reason I think a 4 ohm attenuator works with a 2 ohm load is because I emailed Weber to ask about using a Mini Mass on the 4 ohm setting with a Super Reverb, a 2 ohm load. The guy said it was absolutely fine for the amp and that he has tons of customers that use the Mini Mass with the Super Reverb.

    I guess Ted coined a new term that never existed in engineering before this.

    Regarding the mismatch, good luck. I'm reluctant to tempt fate in a situation that pushes the limits of an amp under the most ideal situation.Ever notice that when you call a company for customer service that you don't get the CEO or chief engineer on the phone? ;)

    Guess I'm confused.. If you "know" the answer and will disagree with people that do not believe this to be the case why did you post the question ?

    Sorry, I didn't mean my post to sound that way. I just meant to say that it was true for a normal switchable attenuators that it would work with a 2 ohm load even if it was a 4 ohm attenuator. My question was if the same was true for one that matches 4, 8, or 16 ohm loads. Sorry :(

    They'll all work, for a while. Or if your only requirement is that they attenuate regardless of whether the amp blows up or not, then they'll always work. ;)

    How about Webers Impedance Matcher? That way everything will match up fine.

    I emailed the guy at Weber and he said the Mass Lite should act as a matcher on it's own. Problem solved. I'll let guys know if anything crazy happens. :)

    Frankly, *I* wouldn't give a rat's rear end what Weber said will work. They're trying to sell you the gizmo. I'd be more interested in what Fender has to say about that set up on *their* amp. After all, they designed the amp, not Weber, and they're the one you're going to be calling when the amp quits on you. Did you speak with Fender? At a minimum, I'd ask an *independent* (and reputable) tech about that.

    I know the thread is a little old but I just wanted to say that I decided to follow your advice and not do it... :)
